Description: The AN/APS-13 Thermal Weapon Sight (TWS) is a second generation FLIR for use on rifles, surveillance missions and shoulder-launched missiles. The PAS-13 can be used to see in total darkness, in adverse weather conditions, and through battlefield smoke and dust. The TWS provides interchangeable telescopes for quick adaptation to any mission. It has video output and has been selected as the sight for the US Army's Land Warrior program. The combat-proven PAS-13 thermal sight is electronically programmable, requires no visible light to operate and will not shut down when hit by direct light. It is lightest enough to be hand-held operated. There are three PAS-13 variants the Light, Medium and Heavy, the LTWS, MTWS and HTWS respectively.
Deliveries to the US Army began in 1998 with the Thermal Omnibus contract, with more than 12,500 units already delivered to the US Army, US Marine Corps and Special Operations Forces. In 2004, the US Army placed four orders (3+1) worth $201 million ($165 million + $36 million) covering deliveries of 11,812 (9,956 + 1,856) in support of US military troops deployments in Afghanistan and Iraq. With the current contracts, Raytheon will have delivered more than 27,000 light, medium and heavy TWS. The AN/PAS-13B(V)3 HTWS can be installed on the M2, M4, M16, Mk19, M24 and M82A2 weapons.
